Electrical resistance wire is a type of wire designed to have a specific and controlled electrical resistance. These wires are primarily used in applications that require controlled heating or precise electrical resistance, such as heating elements, resistors, and electrical components where the flow of electricity needs to be regulated.

Resistivity: Resistance wire materials are chosen for their high resistivity, meaning they oppose the flow of electric current, generating heat in the process. The higher the resistivity, the more heat is generated when current flows through the wire.

Heat Resistance: Resistance wires can withstand high temperatures without degrading. This is particularly important in heating elements, where the wire needs to remain stable and functional at elevated temperatures.

Durability: These wires are designed to resist oxidation and wear, particularly in high-temperature or high-stress environments.

Flexibility: Depending on the material and the application, resistance wires can be flexible or rigid, depending on the specific needs (e.g., for wound or coiled heating elements).
